FACE-PLATE FOR CONCRETE-BLOCK MACHINES.

To all whom t may concern:

Be it known that 1, CHARLES E. PHIL- LIPs, a citizen of the TJnited States, residing at Indianapolis, in the county of Marion and State of Indiana, have invented certain -new and useful Improvements in Face-Plates for Concrete-Block Machines, of which the Vfol-` lowing is a specification.

-This invention relates to face plates employed in machinesfor manufacturing concretev blocks having Vtheir facesdivided by grooves to represent binderjoints so Ythat brick construction can be imitated with the use of these blocks; and the object of the invention consists in the provision `of va face plate of the above character whereby predetermined slots or grooves are formed in the faces of the blocks during their course of manufacture, the slots or grooves being intended to represent the joints formedby the usual binder so that brick construction'can fairly be imitated when the blocks are employed in wall construction.

` A further object of the invention is to provide a .face plate. of the above character whereby slots orV grooves may be formedxin the faces of the blocks during the course of manufacture while the faces of the blocksV of concrete blocks, showing my improvedfaceplate in operative'position d'uring the initial formation of the block. `Fig. 2 is a view similar to Figl except that itvshows the block turnedover on its side and resting upon the pallet and showing the means forforming the slots removed from the block. Fig. '3v is a planVr view of the face plate, the surrounding `parts of theomachine being omitted Fig. 4 isa cross section of the face plate, onthe line A-A in Fig. 3, showing the groove formingbarsrextended above the face of the plate.

Specification of Letters-Patent.

-frame of the machine 'are held in their respective relation by means of a stationary back plate 12 and bolts 13, and said Vplate l2 forms one side of 'the mold box. mold box, lexclusive ofl the Oback plate 12, comprises the face plate 14, end gates 15 and the removable pallet board 16. These' latter 'parts of the mold box are movable through the action of a swinging frame 18 which ispivotally secured to the side members 10 at 19, themachi-nehere shown being of a conventional style in which the operation of molding the blocks is performed with the faces down, so that blockshaving irregular faces and blocks having grooves can not only be successfully molded but can be removed from ythe machine without n- ]ury. As shown in Fig. 3 the faceplate comprises a series Yof sections 14 which are arranged to form a rectangle,l the area of the collective sections being/equivalent to the surface area ofthe face of the block. yThese sections are arranged in their respectiverelation with uniform intervening spaces 205 within which the groove forming member is situated. The sections-14 are held in poe sition by Vmeans of a base plate 22,` the former being heldin advance of the latter by a plurality o f hollow cylinders 24 of imiform length, Vand passing through these hollow cylinders, sections and base plate are bolts 25 by -which all of theparts are heldl together. The groove forming member 21 1s mount-` ed so. as to havel movement independent ofV botlrthe sections 14 and .base plate 22 in order that the projecting 'portion of said member above the surface of the, face plate may :be retracted or removed from the block after the operation ofmolding the latteris completed.v After a block is yremoved from the machine and the parts of the latter are y Patented Feb. 22, 1916.

. Application filed Augtst 27, 1915. serial No. 47,655.

The

resting in the position shown in Fig.v2,the.

frame 18, carrying the face plate, end gates 15 and pallet board 16, is moved into vertical position shown in Fig. 1, preparatory to the molding of the next block. During the movement of the frame 18 the face plate is lowered into the position it occupies in Fig. 1, and just before reaching the vlimit of its travel the ends of the member 21 come into contact with a pair of blocks 30, one of which is located upon each of the side members 10, which arrest the movement of the member 21 slightly in advance of the moving face plate, so that the movement `of the latter is suthciently extended to allow the edges of the groove forming member 21 to project above the surface of the face plate to form grooves 11a of the desired depth in the next block. After the operation of molding the next block is completed the frame 18 is again lowered into the position shown in Fig. 2, the movement of the frame 18 being arrested by means of an arm 31 engaging the lower edge of the back plate 12, at which time the block is resting'upon the pallet board and ready to be removed from the machine. During the operation of turning the block so as to be 'sustained by the pallet board it is desirable to remove the groove forming member 21 from the newly made block to protect the latter from possible injury by the projecting portion of the member 21 above the surface of the face plate.

Movement is imparted to the groove forming member 2l by means of a lever 35 whichl is pivoted in a standard 36 at 37, the end of the lever adjacent to the standard pivotally engaging a. link 38 which extends over and pivotally engages the member 21 at 10. As has heretofore been pointed out, the movement of the member 21to project its upper portion above the surface of the face plate is effected by thelatter coming into contactA with the blocks 30 when the frame 18 is lowered, and it is to retract the member so as to bring it flush with the surface ofthe face plate that comes within the sphere of action of fthe levery 35. After the block is molded and the frame 18 is lowered into f the position shown in Fig. 2', the free end` of the lever 35, immediately7 precedingthe limit of travel of thek frame 18, comes into contact with the lower edge.v of the back,v

plate 12 which :forces said end of the lever -backward, and through the intermediate fulcrum between the point of contact of the free end of the lever and its engagement with the member 21 through the link 38, the member 21 is moved .toward the back plate 1Q a sufficient distance to bring the edge of the member 21 iiusli with the surface of the face plate, leaving the latter smooth and free from obstruction. The newly made block may nov,7 be freely removed from the machine.
